Hawking radiation as a research area investigates the quantum-mechanical particle emission predicted to occur at black hole event horizons, integrating quantum field theory in curved spacetime, general relativity, and thermodynamics. It explores the derivation, robustness, and extensions of Hawking’s original calculation, its implications for black hole thermodynamics, entropy, and temperature, and its central role in the black hole information loss problem. The field also includes studies of analog Hawking radiation in laboratory systems, possible observational signatures of evaporation for primordial or microscopic black holes, and attempts to embed the phenomenon in candidate quantum gravity frameworks such as string theory and holography.
Researchers from Stockholm University and the Indian Institute of Science Education and Research (IISER) Mohali have reported a practical way to spot one of physics' strangest predictions: the Unruh effect, which says that ...

A decade ago, scientists first detected ripples in the fabric of space-time, called gravitational waves, from the collision of two black holes. Now, thanks to improved technology and a bit of luck, a newly detected black ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This framework predicts the ...
Scientists may have found a new way to detect some of the universe's most mysterious objects, primordial black holes (PBHs), using Hawking radiation. This groundbreaking approach relies upon watching for their radiation signatures ...

The universe is decaying much faster than thought. This is shown by calculations of three Dutch scientists on the so-called Hawking radiation. They calculate that the last stellar remnants take about 1078 years to perish. ...

Black hole quantum effects are usually thought to be too small to have any observable signatures. This is indeed the case for heavy black holes, such as the ones detected via gravitational waves by LIGO in 2015. These black ...
The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a subtle signature in gravitational ...
